Chemical Structure
Description
As a certified reference material (CRM), 1-Bromo-2,5,8,11,14-heptadecapentayne meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
1-Bromo-2,5,8,11,14-heptadecapentayne (CAS 93322-84-0), molecular formula C17H15Br and molecular weight 299.21 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Bromo-2,5,8,11,14-heptadecapentayne (C17H15Br) contains bromine substitution, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 299.21 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
